Flutter is definitely the enemy. I was thinking about the GP RV-4 kit having that style of ailerons, too. I think with a pretty firm setup, like servos in each wing, might be ok. BTW, that was a very nice way to remind me.[&:] Don't worry about my feelings though. If I knew it all, I wouldn't be here asking questions. Just don't anybody tell my wife!!!
I'm going to ask alot from this airframe, but I want it to work the first time!


BTW, I think it's about time to hop downstairs and build a 1/2a PBF. It takes about two hours...
